A Modified Permutation Algorithm for Low Complexity Encoding in NB-QC-LDPC Codes

A modified permutation algorithm that optimizes the preprocessing step of the efficient encoding algorithm is proposed for nonbinary quasi-cyclic low-density parity-check (NB-QC-LDPC) codes. Linear complexity encoding is implemented and at least 0.15dB performance loss is avoided.
